County, Pennsylvania (the "Executive");

                                   WITNESSETH:

     WHEREAS, the Executive is currently serving as the Chief Operating Officer
of the Company; and

covenants and agreements of the parties herein contained, and intending to be
legally bound hereby, the parties hereto agree as follows:

1.   DEFINED TERMS.
     -------------

     The definitions of capitalized terms used in this Agreement, unless

Time; provided, that commencing on the second anniversary of the Effective Date

4.   POSITION AND DUTIES.
     -------------------

     During the Term of this Agreement, the Executive shall serve as President
and Chief Operating Officer of the Company and shall also serve in any other
executive officer position of the Company or its subsidiaries and affiliates as
the Board may reasonably request. The Executive shall be the chief operating
officer of the Company and shall have such duties and responsibilities as are
customary for the Executive's position and such other duties not inconsistent
therewith as the Board of Directors may reasonably assign from time to time.
During the Term of this Agreement, excluding any periods of vacation and sick
leave to which the Executive is entitled under the Company's policies and
practices (as the same may be increased in the future), the Executive shall
devote substantially all his working time and efforts to the business and
affairs of the Company and its subsidiaries and affiliates and shall diligently
and faithfully perform his duties to the best of his ability; provided, however,
that the Executive may engage in activities relating to personal matters
(including personal financial matters) and in such corporate, industry, civic
and charitable activities, including membership on corporate and charitable
boards of directors or trustees of non-affiliated companies and organizations,
so long as such service does not substantially interfere with the performance of
his duties hereunder or violate his obligations under Section 10 hereof.

5.   COMPENSATION AND RELATED MATTERS.
     --------------------------------

     5.1 HIRING COMPENSATION. On the Effective Date, the Company shall grant the
         -------------------
Executive 50,000 shares of restricted Common Stock under the Company's Stock
Award Plan, which shares of restricted Common Stock shall vest and shall become
free of restrictions in equal annual installments on the first, second and third
anniversary of the Effective Date. The Executive shall have the opportunity to
make a voluntary deferral election prior to the lapse of the restrictions on
such Common Stock.

     5.2 BASE SALARY. The Company shall pay, or cause to be paid, to the
         -----------
Executive an annual base salary ("Base Salary") during the Term of this
Agreement, which shall be at an initial rate of not less than $600,000 per year.
The Base Salary shall be paid in accordance with the Company's payroll practices
for its senior officers, but not less frequently than monthly, in arrears. For
purposes of this Agreement, "Base Salary" shall include any increases in Base
Salary during the Term of this Agreement. The Base Salary in effect from time to
time shall not be decreased during the Term of this Agreement except in
connection with across-the-board salary reductions similarly affecting all
senior officers of the Company and all senior officers of any person in control
of the Company which have been agreed to by the Executive. Compensation of the
Executive by Base Salary payments shall not be deemed exclusive and shall not
prevent the Executive from participating in any other compensation or benefit
plan of the Company. The Base Salary payments (including any increased Base
Salary payments) shall not in any way limit or reduce any other obligation of
the Company hereunder, and no other compensation, benefit or payment hereunder
shall in any way limit or reduce the obligation of the Company to pay the
Executive's Base Salary.

                                       2
<PAGE>

     5.3 BENEFIT PLANS. During the Term, the Executive and his eligible
         -------------
dependents shall be entitled to participate in and receive benefits under all
"employee benefit plans" (as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended from time to time ("ERISA")), and
employee benefit arrangements in which senior officers of the Company generally
participate, including without limitation, (i) all savings, deferred
compensation, profit sharing and retirement plans, practices, policies and
programs and (ii) all welfare benefit plans, practices, policies and programs
(including all medical, prescription, dental, disability, employee life
insurance, group life insurance, group hospitalization, health, accidental death
and travel accident insurance plans and programs) as are made generally
available to senior officers of the Company, subject to and on a basis
consistent with the terms, conditions and overall administration of such plans,
practices, policies and programs, including provisions which permit such plans,
practices, policies and programs to be modified or terminated, provided, that if
the Company reduces the benefits provided under or terminates any such employee
benefit plan, practice, policy or program in which the Executive participates,
the Company shall offer to the Executive participation in another plan or
program that provides the Executive with benefits at least comparable to those
that were reduced or eliminated. The Executive's participation in such employee
benefit plans, practices, policies and programs shall be at a level appropriate
for the Executive's position. Such employee benefit plans, practices, policies
and programs, shall include, without limitation, the plans, programs, policies
and practices in which the Executive participates on the date of this Agreement.

     5.4 INCENTIVE COMPENSATION. During the Term of this Agreement, the
         ----------------------
Executive shall be entitled to participate in and receive benefits under all
annual incentive (bonus) plans and long-term incentive compensation plans in
which other senior officers of the Company generally participate, including all
restricted share, performance restricted share and stock option plans of the
Company. The Executive's participation in such incentive plans shall be at a
level appropriate for the Executive's position. Without limiting the generality
of the foregoing, the Company shall provide the Executive with an annual
incentive opportunity, as a percentage of the Executive's Base Salary at target
performance levels, that is not less than the opportunity provided to the
Executive on the date of this Agreement, which levels shall be reasonable and
shall be adjusted for extraordinary events. Such incentive compensation shall be
subject to and on a basis consistent with the terms, conditions and overall
administration of such plans, including provisions which permit such plans to be
modified or terminated, provided, that if the Company reduces the incentive
compensation opportunities provided under or terminates any such plan in which
the Executive participates, the Company shall offer to the Executive
participation in another plan that provides the Executive with an incentive
compensation opportunity at least comparable to that which was reduced or
eliminated. Such incentive compensation plans shall include, without limitation,
the plans in which the Executive participates on the date of this Agreement.

     5.5 OTHER BENEFITS. The Executive shall participate on the same terms and
         --------------
conditions as all other senior officers of the Company in all other benefit
plans, programs, or arrangements as may be now or hereafter sponsored or
maintained for senior officers of the Company generally and shall participate on
the same terms and conditions as other senior officers generally participate.

                                       3
<PAGE>

     5.6 FRINGE BENEFITS. During the Term of this Agreement, the Executive shall
         ---------------
be entitled to receive all perquisites and fringe benefits which the Company
makes available to senior officers of the Company generally, including, but not
limited to, all perquisites and fringe benefits provided to the Executive on the
date of this Agreement.

     5.7 EXPENSES. During the Term of this Agreement, the Executive is
         --------
authorized to incur, and shall be reimbursed by the Company for all reasonable
and customary business-related expenses, including travel, entertainment, gifts
and similar items, incurred by the Executive in connection with his employment
hereunder.

     5.8 WORKING FACILITIES. During the Term of this Agreement, the Company
         ------------------
shall furnish the Executive with offices and working facilities in the Company's
principal executive offices and shall provide secretarial and other assistance
suitable to Executive's position and adequate for the performance of his duties
hereunder.

     5.9 VACATION. During the Term of this Agreement, the Executive shall be
         --------
entitled to vacation in accordance with the Company's current policies and
practices, provided that the Executive shall be entitled to not less than five
(5) weeks of vacation during each year of this Agreement, or such greater period
as the Board shall approve, without reduction in salary or other benefits.

     5.10 ANNUAL REVIEW. During the Term of this Agreement, the Board (or the
          -------------
compensation committee of the Board) shall in good faith review the Executive's
total compensation package (including but not limited to the Base Salary
provided for in Section 5.2, the benefit plans provided for in Section 5.3 and
the short and long-term incentive compensation opportunity provided for in
Section 5.4) at least annually for possible increase, taking into account, among
other things, (i) the performance of the Executive, (ii) the performance of the
Company, and (iii) the overall compensation of executives in similar positions
at comparable companies.

6.   COMPENSATION IN THE EVENT OF EXECUTIVE'S DISABILITY.
     ---------------------------------------------------

     During the Term of this Agreement, during any period that the Executive
fails to perform the Executive's full-time duties hereunder as a result of
incapacity due to physical or mental illness, the Company shall pay, or cause to
be paid, to the Executive his Base Salary at the rate in effect at the
commencement of any such period, together with all compensation and benefits
payable to the Executive under the terms of any compensation or benefit plan,
program or arrangement maintained by the Company for the benefit of the
Executive during such period, until this Agreement is terminated by the Company
for Disability; provided, however, that such payments shall be reduced by the
sum of the amounts, if any, payable to the Executive at or prior to the time of
any such payment under disability benefit plans of the Company, which amounts
were not previously applied to reduce any such payment.

7.   TERMINATION COMPENSATION AND BENEFITS.
     -------------------------------------

                                       4
<PAGE>

     7.1 If the Executive's employment is terminated for any reason during the
Term of this Agreement, the Company shall pay to the Executive (or in accordance
with Section 11.2 in the event of the Executive's death), (i) the Executive's
Base Salary through the Date of Termination at the rate in effect immediately
prior to the time the Notice of Termination is given, (ii) all compensation and
benefits (other than severance compensation and benefits) payable to the
Executive through the Date of Termination or thereafter under the terms of any
compensation or benefit plan, program or arrangement maintained by the Company
during such period, including any short-term or long-term incentive compensation
to which the Executive is entitled, by virtue of previous awards, in accordance
with the terms of the long-term incentive plans in which Executive participates,
and (iii) any unreimbursed expenses payable pursuant to Section 5.7 of the
Agreement that were incurred before the Date of Termination.

     7.2 (a) In the event the Executive's employment is terminated during the
Term of this Agreement by the Executive for Good Reason or by the Company for
any reason other than Cause, death of the Executive or Disability, (i) the
Company shall pay the Executive, in addition to amounts payable under Sections
7.1 and 7.3, a lump sum cash payment to be made within thirty (30) days after
the Date of Termination equal to three times (the "Multiplier") the sum of (x)
the higher of the Base Salary in effect immediately prior to the occurrence of
the event or circumstance upon which the Notice of Termination is based or the
Base Salary in effect immediately prior to the date of the Notice of
Termination, and (y) the highest of the annual bonus that may be earned by the
Executive if target performance levels are achieved in the year in which the
Date of Termination occurs or the highest annual bonus earned by the Executive
in respect of the three (3) years immediately preceding the year in which the
Date of Termination occurs, in any case, pursuant to any annual incentive
(bonus) plan maintained by the Company, (ii) the restricted Common Stock awarded
to the Executive pursuant to Section 5.1 shall vest and shall become free of
restrictions upon the Date of Termination and (iii) the Company shall continue
the benefits provided for in Section 5.3 of this Agreement for thirty-six (36)
additional months after the Date of Termination. The payments provided for in
this Section 7.2(a) shall be in lieu of any severance compensation to which the
Executive would otherwise be entitled under any severance plan or policy
applicable to the Executive.

         (b) In the event that the Company gives notice to the Executive in
accordance with Section 3 of the Agreement that this Agreement shall not be
extended and will terminate at the end of the then current Term, then (i) the
Company shall, within thirty (30) days after the end of the Term, pay the
Executive a lump sum cash payment in an amount determined in accordance with
Section 7.2(a)(i) except that the Multiplier shall be one and one-half (1-1/2)
instead of three (3), (ii) the restricted Common Stock awarded to the Executive
pursuant to Section 5.1 shall vest and shall become free of restrictions at the
end of the Term, and (iii) the Company shall continue the benefits provided for
in Section 5.3 of this Agreement for eighteen (18) additional months after the
end of the Term. The payments provided for in this Section 7.2(b) shall be in
lieu of any severance compensation to which the Executive would otherwise be
entitled under any severance plan or policy applicable to the Executive.

     7.3 If the Executive's employment is terminated for any reason during the
Term of this Agreement, the Company shall pay the Executive's normal
post-termination compensation

                                       5
<PAGE>

and benefits (other than severance compensation and benefits) to the Executive
as such payments become due. Such normal post-termination compensation and
benefits (other than severance compensation and benefits) shall be determined
under, and paid in accordance with the Company's retirement, insurance and other
compensation or benefit plans, programs and arrangements (other than this
Agreement), as applicable.

     7.4 (a) Anything in this Agreement to the contrary notwithstanding, in the
event it shall be determined that any payment, benefit, or distribution by the
Company or its affiliates to or for the benefit of the Executive, whether paid
or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise (a "Payment"), would be subject to the excise tax imposed
by Section 4999 of the Code, or any interest or penalties with respect to such
excise tax (such excise tax, together with any such interest and penalties, are
hereinafter collectively referred to as the "Excise Tax"), then the Executive
shall be entitled to receive an additional payment ("Gross-Up Payment") in an
amount such that after payment by the Executive of all taxes (including any
interest or penalties imposed with respect to such taxes), including, without
limitation, any income taxes and Excise Tax imposed upon the Gross-Up Payment,
the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments.

         (b) Subject to the provisions of Section 7.4(c) hereof, all
determinations required to be made under this Section 7.4, including whether a
Gross-Up Payment is required and the amount of such Gross-Up Payment and the
assumptions to be used in arriving at such determinations, shall be made by the
Company's principal outside accounting firm (the "Accounting Firm") which shall
provide detailed supporting calculations both to the Board and the Executive
within fifteen (15) business days after the Date of Termination and/or such
earlier date(s) as may be requested by the Company or the Executive (each such
date and the Date of Termination shall be referred to as a "Determination Date"
for purposes of this Section 7.4(b) and Section 7.5 hereof). All fees and
expenses of the Accounting Firm shall be borne solely by the Company. The
initial Gross-Up Payment, if any, as determined pursuant to this Section 7.4(b),
shall be paid by the Company to the Executive within thirty (30) days of the
receipt of the Accounting Firm's determination. If the Accounting Firm
determines that no Excise Tax is payable by the Executive, it shall furnish the
Executive with a written opinion that failure to report the Excise Tax on the
Executive's applicable federal income tax return would not result in the
imposition of a negligence or similar penalty. Any determination by the
Accounting Firm under this Section 7.4(b) shall be binding upon the Company and
the Executive. As a result of the uncertainty in the application of Section 4999
of the Code at the time of the initial determination by the Accounting Firm
hereunder, it is possible that Gross-Up Payments which will not have been made
by the Company should have been made ("Underpayment") consistent with the
calculations required to be made hereunder. In the event that the Company
exhausts its remedies pursuant to Section 7.4(c) and the Executive thereafter is
required to make a payment of any Excise Tax, the Accounting Firm shall
determine the amount of the Underpayment that has occurred and any such
Underpayment shall be promptly paid by the Company to or for the benefit of the
Executive.

         (c) The Executive shall notify the Company in writing of any claim by

                                       6
<PAGE>

the Internal Revenue Service that, if successful, would require the payment by
the Company of an Underpayment. Such notification shall be given as soon as
practicable but no later than ten (10) business days after the Executive is
informed in writing of such claim and shall apprise the Company of the nature of
such claim and the date on which such claim is requested to be paid. The
Executive shall not pay such claim prior to the expiration of the thirty (30)
day period following the date on which he gives such notice to the Company (or
such shorter period ending on the date that any payment of taxes with respect to
such claim is due). If the Company notifies the Executive in writing prior to
the expiration of such period that it desires to contest such claim, the
Executive shall:

          (i) give the Company any information reasonably requested by the
Company relating to such claim;

          (ii) take such action in connection with contesting such claim as the
Company shall reasonably request in writing from time to time, including,
without limitation accepting legal representation with respect to such claim by
an attorney reasonably selected by the Company;

          (iii) cooperate with the Company in good faith in order to effectively
contest such claim; and

          (iv) permit the Company to participate in any proceeding relating to
such claim; provided, however, that the Company shall bear and pay directly all
costs and expenses (including additional interest and penalties) incurred in
connection with such contest and shall indemnify and hold the Executive
harmless, on an after-tax basis, for any Excise Tax or income tax, including
interest and penalties with respect thereto, imposed as a result of such
representation and payment of costs and expenses. Without limitation on the
foregoing provisions of this Section 7.4(c), the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may
pursue or forgo any and all administrative appeals, proceedings, hearings and
conferences with the taxing authority in respect of such claim and may, at its
sole option, either direct the Executive to pay the tax claimed and sue for a
refund or contest the claim in any permissible manner, and the Executive agrees
to prosecute such contest to a determination before any administrative tribunal,
in a court of initial jurisdiction and in one or more appellate courts, as the
Company shall determine; provided, however, that if the Company directs the
Executive to pay such claim and sue for a refund, the Company shall advance the
amount of such payment to the Executive on an interest-free basis and shall
indemnify and hold the Executive harmless, on an after-tax basis, from any
Excise Tax or income tax, including interest or penalties with respect thereto,
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and provided, further, that any extension of the
statute of limitations relating to payment of taxes for the taxable year of the
Executive with respect to which such contested amount is claimed to be due is
limited solely to such contested amount. Furthermore, the Company's control of
the contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder and the Executive shall be entitled to settle or
contest, as the case may be, any other issue raised by the Internal Revenue
Service or any other taxing authority.

                                       7
<PAGE>

          (d) If, after the receipt by the Executive of an amount advanced by
the Company pursuant to Section 7.4(c) hereof, the Executive becomes entitled to
receive any refund with respect to such claim, the Executive shall (subject to
the Company's compliance with the requirements of Section 7.4(c) hereof)
promptly pay to the Company the amount of such refund (together with any
interest paid or credited thereon after taxes applicable thereto). If, after the
receipt by the Executive of an amount advanced by the Company pursuant to
Section 7.4(c) hereof, a determination is made that the Executive shall not be
entitled to any refund with respect to such claim and the Company does not
notify the Executive in writing of its intent to contest such denial of refund
prior to the expiration of thirty (30) days after such determination, then such
advance shall be forgiven and shall not be required to be repaid.

     7.5 The payments provided for in Section 7.4 hereof (other than Section
7.4(c) and (d)) shall be made not later than the thirtieth (30th) day following
each Determination Date; provided, however, that if the amounts of such payments
cannot be finally determined on or before such day, the Company shall pay to the
Executive on such day an estimate, as determined by the Executive, of the
minimum amount of such payments to which the Executive is clearly entitled and
shall pay the remainder of such payments (together with interest at the rate
provided in Section 1274(b)(2)(B) of the Code) as soon as the amount thereof can
be determined but in no event later than the forty-fifth (45th) day after each
Determination Date. In the event that the amount of the estimated payments
exceeds the amount subsequently determined to have been due, such excess shall
constitute a loan by the Company to the Executive, payable on the fifth (5th)
business day after demand by the Company (together with interest at the rate
provided in Section 1274(b)(2)(B) of the Code).

8.   TERMINATION PROCEDURES.
     ----------------------

     8.1 NOTICE OF TERMINATION. During the Term of this Agreement, any purported
         ---------------------
termination of the Executive's employment (other than by reason of death) shall
be communicated by written Notice of Termination from one party hereto to the
other party hereto in accordance with Section 12 hereof. For purposes of this
Agreement, a "Notice of Termination" shall mean a notice which shall indicate
the specific termination provision in this Agreement relied upon and, in the
case of a termination by the Company for Cause or by the Executive for Good
Reason, shall set forth in reasonable detail the facts and circumstances claimed
to provide a basis for termination of the Executive's employment under the
provision so indicated. Further, a Notice of Termination for Cause is required
to include a copy of a resolution duly adopted by the affirmative vote of not
less than three-quarters (3/4) of the entire membership of the Board at a
meeting of the Board which was called and held for the purpose of considering
such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with the Executive's counsel, to be heard before the
Board) finding that, in the good faith opinion of the Board, the Executive was
guilty of conduct set forth in the definition of Cause herein, and specifying
the particulars thereof in detail.

     8.2 DATE OF TERMINATION. "Date of Termination," with respect to any
         -------------------
purported termination of the Executive's employment during the Term of this
Agreement, shall

                                       8
<PAGE>

mean (i) if the Executive's employment is terminated by his death, the date of
his death, (ii) if the Executive's employment is terminated by the Executive
other than for Good Reason, the date specified in the Notice of Termination
(which shall not be less than one hundred eighty (180) days) after such Notice
of Termination is given, (iii) if the Executive's employment is terminated by
the Company for Cause, on the date that the Notice of Termination is sent by the
Board in accordance with Section 8.1, and (iv) if the Executive's employment is
terminated for any other reason, the date specified in the Notice of Termination
(which shall not be less than sixty (60) days) after such Notice of Termination
is given.

9.   NO MITIGATION.
     -------------

     The Company agrees that, if the Executive's employment hereunder is
terminated during the Term of this Agreement, the Executive is not required to
seek other employment or to attempt in any way to reduce any amounts payable to
the Executive by the Company hereunder. Further, the amount of any payment or
benefit provided for hereunder (other than pursuant to Section 7.4(d) hereof)
shall not be reduced by any compensation earned by the Executive as the result
of employment by another employer, by retirement benefits, by offset against any
amount claimed to be owed by the Executive to the Company, or otherwise.

10.  CONFIDENTIALITY AND NONCOMPETITION.
     ----------------------------------

     10.1 The Executive shall not, during or after the Term of this Agreement,
without the prior written consent of the Company disclose to any entity or
person any information which is treated as confidential by the Company or any of
their subsidiaries or affiliates (each, a "Company Entity"), and is not
generally known or available in to the public, provided, that the Executive may
make disclosures of such confidential information (i) during the Term of this
Agreement in the course of and to the extent required by and consistent with the
performance of his duties hereunder, and (ii) to the extent required by law or
legal process.

     10.2 Except as permitted by the Company with its prior written consent, the
Executive shall not, during the Executive's employment with the Company and for
the period ending twenty-four (24) months after the Executive's employment with
the Company terminates for any reason, directly or indirectly, own, enter into
the employ of or render, any services (whether as a consultant or otherwise) to
any person, firm or corporation within the United States or any foreign country
in which the Company is doing or is contemplating doing business on the Date of
Termination which is a competitor of any Company Entity with respect to products
which any Company Entity is then producing or services which any Company Entity
is then providing (a "Competitor"), or approach, canvass, solicit, or otherwise
endeavor to entice away from the Company, any customer in respect of any service
or product in any way competitive with the services or products supplied by any
Company Entity to such customer, or solicit the services of, or endeavor to
entice away from the Company, any director, executive officer or employee of the
Company; provided, that it shall not be a violation of this provision for the
Executive to be employed by, or render services to, a Competitor, if the
Executive renders those services only with respect to those lines of business of
the Competitor which are not directly competitive with

                                       9
<PAGE>

a line of business of any Company Entity or are located in any country in which
the Company does not do business and was not contemplating doing business on the
Date of Termination.

     10.3 The Executive acknowledges and agrees that any breach of this Section
10 by the Executive will result in immediate and irreparable harm to the
Company, the amount of which will be extremely difficult to ascertain, and that
the Buyer could not be reasonably or adequately compensated by damages in an
action at law. For these reasons, the Company shall have the right to obtain
such preliminary, temporary or permanent mandatory or restraining injunctions,
orders or decrees as may be necessary to protect the Company against or on
account of any breach by the Executive of the provisions of this Section 10
without proof of any actual damage caused to the Company.

11.  SUCCESSORS; BINDING AGREEMENT.
     -----------------------------

     11.1 In addition to any obligations imposed by law upon any successor to
the Company, the Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company, as the case may be, to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. Failure of the Company to obtain such assumption and agreement
upon the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Executive to compensation from the Company in
the same amount and on the same terms as the Executive would be entitled to
hereunder if the Executive were to terminate the Executive's employment for Good
Reason, except that, for purposes of implementing the foregoing, the date on

     If the Executive, in his capacity as an officer, approves in writing, or if
the Executive is elected as a director, if the Executive, in his capacity as a
director, votes for any action that will adversely affect the Executive's rights
under this Agreement, such vote or approval shall be deemed to constitute the
Executive's consent to such action under this Agreement; otherwise, no provision
of this Agreement may be modified, waived or discharged unless such waiver,
modification or discharge is agreed to in writing and signed by the Executive
and such officers as may be specifically designated by the Board. No waiver by
any party hereto at any time of any breach by any other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed by
such other party shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time. No agreements or
representations, oral or otherwise, express or implied, with respect to the
subject matter hereof have been made by any party which are not expressly set

parties hereto in respect of the subject matter contained herein and supersedes
all prior agreements, promises, covenants, arrangements, communications,
representations or warranties, whether oral or written, by any officer, employee
or representative of any party hereto; and any prior agreement of the parties
hereto in respect of the subject matter contained herein is hereby terminated
and canceled, except as otherwise provided in this Agreement. Nothing in this
Section 13 shall affect the Executive's rights under the Change in Control
Agreement or the Indemnification Agreement between the Company and the

successor provisions to such sections. There shall be withheld from any payments
provided for hereunder any amounts required to be withheld under federal, state
or local law and any additional withholding amounts to which the Executive has

which by their nature and terms require satisfaction after the end of the Term
shall survive such event and shall remain binding upon such party.

Agreement, which shall remain in full force and effect.

15.  COUNTERPARTS.

     This Agreement may be executed in several counterparts, each of which shall
be deemed to be an original but all of which together will constitute one and

16.  SETTLEMENT OF DISPUTES; ARBITRATION.

writing and shall be directed to and initially determined by the Board. Any
denial by the Board of a claim for benefits under this Agreement shall be
delivered to the Executive in writing and shall set forth the specific reasons
for the denial and the specific provisions of this Agreement relied upon. The
Board shall afford a reasonable opportunity to the Executive for a review of the
decision denying a claim and shall further allow the Executive to appeal to the
Board a decision of the Board within sixty (60) days after notification by the
Board that the Executive's claim has been denied. To the extent permitted by
applicable law and subject to the right of the Company to seek equitable relief
in a court pursuant to Section 10.3, any further dispute or controversy arising
under or in connection with this Agreement shall be settled exclusively by

     -----------------

     The Company shall pay to the Executive all reasonable legal fees and
expenses incurred by the Executive in disputing any termination or in seeking in
good faith to obtain or enforce any benefit or right provided by this Agreement
or in connection with any tax audit or proceeding to the extent attributable to
the application of Section 4999 of the Code to any payment or benefit provided
hereunder; provided, however, the Company shall not be required to pay to the
Executive legal fees and expenses to the extent such legal fees and expenses
were incurred in connection with a contest controlled by the Company pursuant to
Section 7.4(c) hereof in connection with which the Company complied with its
obligations under said Section 7.4(d). Such payments shall be made within thirty
(30) business days after delivery of the Executive's written request for payment
accompanied with such evidence of fees and expenses incurred as the Company
reasonably may require.

18.  COORDINATION OF BENEFITS.

     Notwithstanding anything in this Agreement to the contrary, if the

between the Company and the Executive in connection with a Change in Control (as
defined therein), then this Agreement (including Section 10.2 hereof) shall
forthwith terminate and the Executive shall not be entitled

to the payment of any amounts under this Agreement other than pursuant to
Section 7.1 hereof (and any amounts theretofore paid to the Executive pursuant

     (c) "Cause" for termination by the Company of the Executive's employment,
for purposes of this Agreement, shall mean (i) the willful and continued failure

(other than any such failure resulting from the Executive's incapacity due to
physical or mental illness or any such actual or anticipated failure after the

which is demonstrably and materially injurious to the Company, monetarily or
otherwise, including but not limited to fraud or embezzlement by the Executive,
or (iii) the Executive's conviction (or entering into a plea bargain admitting
guilt) of any felony, or (iv) a material breach by the Executive of this
Agreement, including a violation of Section 10. For purposes of clauses (i) and

not in good faith and without reasonable belief that the Executive's act, or
failure to act, was in the best interest of the Company.

     (d) "Code" shall mean the Internal Revenue Code of 1986, as amended from
time to time.

     (e) "Date of Termination" shall have the meaning stated in Section 8.2

full-time performance of the Executive's duties hereunder for a period of six
(6) consecutive months.

     (i) "Good Reason" for termination by the Executive of the Executive's
employment shall mean the occurrence (without the Executive's express written
consent), of any one of the following acts by the Company, or failures by the
Company to act, unless, in the case of any act or failure to act described in
paragraphs (i) or (ii) below, such act or failure to act is corrected prior to
the Date of Termination specified in the Notice of Termination given in respect
thereof:

          (i) the assignment to the Executive of any duties inconsistent with
the Executive's status as an executive officer of the Company or a substantial
alteration in the nature or status of the Executive's responsibilities
consistent with the title set forth in Section 4, unless the Executive has
indicated to the Company his intention to terminate his employment prior to the
end of the Term, and such assignment or alteration is made by the Board in good
faith in order to facilitate a transition to successor management;

          (ii) any material breach of any provision of this Agreement by the
Company;

          (iii) the relocation of the Executive's principal place of employment

than such principal place of employment (or permitted relocation thereof) except
for required travel on the Company's business to an extent substantially
consistent with the Executive's present business travel obligations;

          (iv) a reduction by the Company in the Executive's Base Salary as in
effect on the date hereof or as the same may be increased from time to time
except for across-the-board salary reductions similarly affecting all senior
officers of the Company and all senior officers of any person in control of the
Company; or

          (v) the failure by the Company to continue in effect any employee
benefit plan or incentive compensation plan in which the Executive currently
participates which is material to the Executive's total compensation, unless
such plan or arrangement has been replaced by a new plan on a basis not
materially less favorable, both in terms of the amount or timing of payment of
benefits provided and the level of the Executive's participation relative to
other participants.

          The Executive's right to terminate the Executive's employment for Good
Reason shall not be affected by the Executive's incapacity due to physical or
mental illness. The Executive's continued employment shall not constitute
consent to, or a waiver of rights with respect to, any act or failure to act
constituting Good Reason hereunder.

     (j) "Gross-Up Payment" shall have the meaning stated in Section 7.4(a)
hereof.

     (k) "Notice of Termination" shall have the meaning stated in Section 8.1
